FUNCTION 
(default setting 
/ value)
DESCRIPTION
Picture Mode
(PC: 
Dynamic;
YPbPr/ S-
Video/ Video: 
Standard)Pre-defined application modes are provided so you can optimize your 
projector image set-up to suit your program type.
You can use the remote control Mode button to select a predefined 
application mode. See Selecting a picture mode on page 31 for 
details.
Color Temp 
(depends on 
the selected 
Application 
mode)
There are four color temperature* settings available.
1.T1: With the highest color temperature, T1 makes the image appear 
the most bluish white than other settings.
2.T2: Makes images appear bluish white.
3.T3: Maintains normal colorings for white.
4.T4: Makes images appear reddish white.
*About color temperatures:
There are many different shades that are considered to be “white” for 
various purposes. One of the common methods of representing white 
color is known as the “color temperature”. A white color with a low color 
temperature appears to be reddish white. A white color with a high color 
temperature appears to have more blue in it.
Brightness 
(depends on 
the selected 
input source)
Adjusts the brightness of the image. The higher the value, the brighter the 
image. And lower the setting, darker the image. Adjust this control so the 
black areas of the image appear just as black and that detail in the dark 
areas is visible. 
Contrast 
(depends on 
the selected 
input source)
Adjusts the degree of difference between dark and light in the image. The 
higher the value, the greater the contrast. Use this to set the peak white 
level after you have previously adjusted the Brightness setting to suit your 
selected input and viewing environment.

page 29 for more information.
Auto Resize 
(on)
Automatically resizes the input signal pixel resolution to the native resolution 
of the projector.
On: The pixel resolution of the input signal is converted to the native 
resolution of the projector (1024 x 768). For input signals with lower 
resolutions, gaps in the pixels are automatically interpolated into the image 
before being projected. This may distort the image clarity.
Off: If larger than the native resolution of the projector, the image is resized to 
fit within the display area. For input signals with lower resolutions, the 
projected image will display smaller than if resized to full screen. You could 
adjust the zoom setting or move the projector towards the screen to increase 
the image size if necessary. You may also need to refocus the projector after 
making these adjustments. 
Aspect Ratio

the selected 
input 
source)Adjusts the video input clock to synchronise with 
the video signal. This helps reduce image distortion 
produced by some PC video timings.

High Altitude 
Mode (off)
A mode for operation in areas like high altitude or high temperature. We 
recommend you use the High Altitude Mode when your environment is 
higher than 3000 feet above sea level, or is hotter than 40
°C, or whenever 
the projector will be used for extended periods of time (>10 hours) 
without shutdown.
To activate the High Altitude Mode, select On by pressing Left 3/Right 
4on the projector or remote control. A confirmation message displays. 
Press6.
Next time you turn on the projector, it will show a message pictured below 
as a reminder during the start-up.
Operation under High Altitude Mode may cause a higher decibel 
operating noise level because of increased fan speed necessary to improve 
overall system cooling and performance.
If you use this projector under other extreme conditions excluding the 
above, it may display auto shut-down symptoms, which is designed to 
protect your projector from over-heating. In cases like this, you should 
switch to High Altitude mode to solve these symptoms. However, this is 
not to state that this projector can operate under any and all harsh or 
extreme conditions.
Auto Off
This function allows the projector to turn off automatically if no input 
signal is detected after a set period of time. Press Left 3/Right 4on the 
projector or remote control to set the duration before the projector is 
turned off. 
Economic 
Mode (off)
Use this mode to reduce system noise and reduce power consumption by 
20%. If this mode is activated, the light output will be reduced and result 
in darker projected images.
Setting the projector in Economic mode extends the lamp timer 
automatic shutdown feature. For more information on how the total 
lamp hour is calculated, see Calculation of lamp hour on page 47.
Presentation 
TimerHelps to remind the presenter to finish the presentation within a certain 
timeframe. Refer to Setting the presentation timer on page 35 for more

Maintenance
Care of the projector
Your projector needs little maintenance. The only thing you need to do on a regular basis is 
to keep the lens clean.
Never remove any parts of the projector except the lamp. Contact your dealer if other parts 
need replacing.
Cleaning the lens
Clean the lens whenever you notice dirt or dust on the surface. 
• Use a canister of compressed air to remove dust. 
• If there is dirt or smears, use lens-cleaning paper or moisten a soft cloth with lens cleaner 
and gently wipe the lens surface.
Never rub the lens with abrasive materials.
Cleaning the projector case
Before you clean the case, turn the projector off using the proper shutdown procedure as 
described in Shutting down the projector on page 36 and unplug the power cord.
• To remove dirt or dust, wipe the case with a soft, lint-free cloth.
• To remove stubborn dirt or stains, moisten a soft cloth with water and a neutral pH 
detergent. Then wipe the case.
Never use wax, alcohol, benzene, thinner or other chemical detergents. These can damage the 
case.
